PVDF film, PVDF transparent film
PVDF (polyvinylidene fluoride) is a kind of light fluoride
material, with the working temperature ranging from -70 to 150 . It
features superior corrosion resistance, mechanical property,
electrical insulating property, low friction coefficient,
weatherability, and radiation tolerance. Moreover, the tensile
strength is two times higher than PTFE, the compressive strength
six times higher than PTFE, and the abrasion resistance similar to
nylon. Properties Color:white ,transparent Surface :Mat , coronatreated - Perfect weather fastness and UVioresistance aging ,over 3000hours
long life - Perfect flat film surface ,easy for second progress.
- Lower moisture transmittance
- outstanding bond&compound property ,especially good compound
effect with PET film,sheet. And EVA film . - Perfect mechanical property ,especially tearing strength of
transverse and portrait . - High cost performance Application: Usage Photovoltaic industry:Solar cell backsheet film. Interior decoration : inner decoration of Automobile,train,aircraft
etc. Electrical apparatus insulation:In electrical field, it can
replacePC,PET,PP etc traditional materials. Intelligence: Kinds of sensors. Advertisement: Advertisement balloon etc. Automobile:material of protecting fuel line. Building thermo insulation material : The out layer thermo
insulation of outer wall . Solar cell back sheet,constructure,greenhouse,semiconductior
sealing and packing,electric,chemical,advertisement etc. Packing:air bubble film damping packing Specification : Thickness:20-50micron Width : 200-1200mm Roll length :100-2000m , and can be customized Storage condition:ventilate ,dry ,moistureproof ,heetproof ,prevent pressure.
